IMPROVEMENT IN MACHINES FOR UNITING SOLES OF BOOTS AND SHOES.

Specification forming part of Letters Patent N 0. 132,493, dated October22, 1872.

To all whom it may concern:

Be it known that I, ANDREW A. REED, of North Bridgewater, in the countyof Plymouth and State of Massachusetts, have invented an Improvement inPreparing Patterns for Boot and Shoe Sole Nailing Machines; and I dohereby declare that the following, taken in connection with the drawingwhich accompanies and forms part of this specification, is a descriptionof my invention sufficient to enable those skilled in the art topractice it.

In nailing boots or shoes with nails cut in and by the nailing-machine,from wire or wirelike material, various means have been employed orinvented for varying the lengths of the nails out in accordance with thevarying thickness of the parts to be united by them,-

and as most of these means are shown in different patents it isunnecessary herein to particularize them, or to otherwise refer to themthan to say that in all of these methods now in use or known to me, theshoe itself or a pattern forming part of the machine, or the skill ofthe operator, constitutes the means employed.

In my invention I use a pattern consisting of a series of slides thatare positioned by means of the shoe itself in a special machine for thatpurpose, these slides being placed or positioned by a caliperingmechanism that measures the thickness all around the sole and transfersthese measurements, as the shoe is moved, to a wheel that moves incorrespondence with the movements of the shoe, said wheel carrying themovable slides, so that as the shoe and wheel are turned the severalslides are successively set in accordance with the varying thickness ofthe sole, this wheel being subsequently moved to the nailing-machine,and the series of set and clamped slides then form- 'ing the pattern, bymeans of which any number of similarly-soled shoes may be nailed withnails, each gaged by the machine to a length corresponding to thethickness of the parts to be united by it. My present inventionconsists, primarily, in automatically setting the movable slides of apattern-wheel by means of the varying thickness of the soles, or bycalipering the soles for the inside to the outside of the soles, andtransferring the variations in distance between the calipering points tothe movable slides of the pattern-wheel.

The drawing represents in side and in front elevation a machineembodying the invention.

a denotes a standard; b c, bearings that support a horizontal shaft, d,having at its front end a feed-wheel, e.- f denotes a vertical posthaving upon its top a horn, g, the upper part of which enters andsupports the shoe, as in a common Blake or McKay sole-sewing machine orsole-nailing machine. The post f turns in suitable bearings and alsoslides vertically in them, and it and its horn g are pressed up by asuitable spring, h, the pressure causing the sole to be griped betweenthe top of the horn and the feed-wheel c, the horn of course yieldingvertically as the thickness fed between it and the wheel varies, and thetop' of the horn always keeping up to the surface of the inner sole, andalso keeping the outer surface of the outer sole against the feed-wheel.The shaft 61 carries a bevel-wheel, z, meshing into and driving abevel-wheel, k, fixed upon the top of a vertical shaft, l', at the footof which shaft 1 is a gear-pinion, m, meshing into and'driving a gear,a, on the bottom of the pattern or slide-wheel 0. This wheel turns on avertical stud-pin, 1;, being held thereon by a nut, q, and carriesaround its perimeter a series of slides, o. The shanks of the slidespass through holes in the wheel, and their upper ends are confinedwithin and by a band, 8, which band may be tightened or loosened by ascrew, 15. When the slides are to beset the band is loosenedsufficiently to permit the slides to move easily, but soas to beretained in position by friction. Extending from the post is an arm, a,at the end of which is an incline or tooth, c, which, when a shoe isplaced upon the horn, is brought down into the plane of the tops of theslides, and so as to rest or press upon the tops of the slides directlybeneath it; and, if the thinnest part of the sole is first broughtbetween the horn and the feed-wheel, and the slides are all raised,then, as the shoe is moved around by the feed-wheel to bring the entireline to be pegged beneath the wheel, the conjoint movement of thepattern-wheel will cause each slide to be set by the tooth, accordinglyas said toothis moved down by the increasing thickness of such parts.

In starting the machine a suitable indexmark on the wheel is broughtunder a pointer, w, and by using the same mark in setting the wheel inthe nailing-machine, to commence to nail by, the wheel forms a perfectpattern to nail the same shoe, or others like it, with nails each equalin length to the thickness of parts it is to unite.

I claim- 1.- In combination with shoe-feed and shoesupporting devices, apattern slide-wheel, rotated by the mechanism that feeds the shoe, andhaving slides which are automatically positioned by therotative movementof the wheel, and relative vertical movements of the parts betweenwhich. the shoe is fed, substantially as shown and described.

2. The wheel having the series of slides, substantially as shown, andfor the purpose described.

3. The combination of the shafts and their gears and. feed-wheel, therotative and vertically-moving shaft f and horn g, and the tooth 'v forsimultaneously feeding the shoe and settingthe slides of thepattern-wheel, substantially as shown and described. lslzilxecnted this7th day of September, A. D.
